Investors are anxiously waiting for Nvidia’s (NVDA) fourth-quarter earnings report, which may provide a much-needed boost to the U.S. stock

Nvidia options pricing on Wednesday afternoon suggested traders expect shares to move roughly $10, or about 8%, in either direction around Wednesday’s earnings, which would be the stock's biggest post-earnings move since May.

Nvidia is slated to report its fiscal fourth-quarter results after the market closes tomorrow. Analysts on average expect the company to report that its Q4 EPS rose to 85 cents from 52 cents during the same period a year earlier.
